CLEAN COAL TECHNOLOGIES

NOx emissions abatement and control by flue gas treatment

Flue gas treatment for NOx control can be categorised into three areas:

selective catalytic reduction (SCR)
selective non-catalytic reduction (SNCR)
combined SO2/NOx control systems

The summarised descriptions of NOx control technologies are mainly drawn from the detailed IEA Coal Research review on NOx emissions abatement and control by Soud and Fukasawa (1996).
